Twelve female subjects were fed a controlled diet, with crackers before every meal. There were four different kinds of crackers: control, bran fiber, gum fiber, and a combination of both bran and gum fiber. Over the course of the study, each subject ate all four kinds of crackers, one kind at a time, for a stretch of several days. The order was randomized. The response is the number of digested calories, measured as the difference between calories eaten and calories passed through the system.
